Abstract
Compositions having enhanced gas and drug transporting capability, are prepared by providing a perfluoro compound dispersed in an aqueous medium with a surfactant to form an aqueous initial dispersion, concentrating the perfluoro compound phase of the dispersion as by centrifugation or filtration, wherein a portion of the surfactant remains complexed with the particles of the peifluoro compound phase and the balance of the surfactant is in the aqueous phase, separating the phases, and redispersing the particles of the concentrated perfluoro compound phase to form a final dispersion in which a major portion of the surfactant is complexed with the perfluoro compound particles.
